           -s, --shuffle   Run the tests in a random order
               --strap     Define strap class to use
           -T              Enable tainting checks
           -t              Enable tainting warnings
               --timer     Print elapsed time after each test file
           -v, --verbose   Display standard output of test scripts while running them
           -V, --version   Display version info

       Single-character options may be stacked.  Default options
       may be set by specifying the PROVE_SWITCHES environment
       variable.

OVERVIEW
       prove is a command-line interface to the test-running
       functionality of "Test::Harness".  With no arguments, it
       will run all tests in the current directory.

       Shell metacharacters may be used with command lines
       options and will be exanded via "File::Glob::bsd_glob".

PROVE VS. "MAKE TEST"
       prove has a number of advantages over "make test" when
       doing development.

       o   prove is designed as a development tool

           Perl users typically run the test harness through a
           makefile via "make test".  That's fine for module
           distributions, but it's suboptimal for a
           test/code/debug development cycle.

       o   prove is granular

           prove lets your run against only the files you want to
           check.  Running "prove t/live/ t/master.t" checks
           every *.t in t/live, plus t/master.t.

       o   prove has an easy verbose mode

           prove has a "-v" option to see the raw output from the
           tests.  To do this with "make test", you must set
           "HARNESS_VERBOSE=1" in the environment.

       o   prove can run under taint mode

           prove's "-T" runs your tests under "perl -T", and "-t"
           runs them under "perl -t".

       o   prove can shuffle tests

           You can use prove's "--shuffle" option to try to
           excite problems that don't show up when tests are run
           in the same order every time.

       o   prove doesn't rely on a make tool

           Not everyone wants to write a makefile, or use
           ExtUtils::MakeMaker to do so.  prove has no external
           dependencies.

       o   Not everything is a module

           More and more users are using Perl's testing tools
           outside the context of a module distribution, and may
           not even use a makefile at all.

COMMAND LINE OPTIONS
       -b, --blib

       Adds blib/lib to the path for your tests, a la "use blib".

       -d, --debug

       Include debug information about how prove is being run.
       This option doesn't show the output from the test scripts.
       That's handled by -v,--verbose.

       -D, --dry

       Dry run: Show the tests to run, but don't run them.

       -I

       Add libraries to @INC, as Perl's -I.

       -l, --lib

       Add "lib" to @INC.  Equivalent to "-Ilib".

       --perl

       Sets the "HARNESS_PERL" environment variable, which
       controls what Perl executable will run the tests.

       -r, --recurse

       Descends into subdirectories of any directories specified,
       looking for tests.

       -s, --shuffle

       Sometimes tests are accidentally dependent on tests that
       have been run before.  This switch will shuffle the tests
       to be run prior to running them, thus ensuring that hidden
       dependencies in the test order are likely to be revealed.
       The author hopes the run the algorithm on the preceding
       sentence to see if he can produce something slightly less
       awkward.

       --strap

       Sets the HARNESS_STRAP_CLASS variable to set which
       Test::Harness::Straps variable to use in running the
       tests.

       -t

       Runs test programs under perl's -t taint warning mode.

       -T

       Runs test programs under perl's -T taint mode.

       --timer

       Print elapsed time after each test file

       -v, --verbose

       Display standard output of test scripts while running
       them.  Also sets TEST_VERBOSE in case your tests rely on
       them.

       -V, --version

       Display version info.
